Patent AT-E104812-T1 (AT)
Inventor: DOERWALD B CLAUS
IPC: H02M5/257

Abstract: When using phase control of semiconductor valves (4) for controlling AC voltage converters, in order to regulate the power factor it is necessary to determine the phase angle between the current I and the voltage U by measuring the time difference between the points at which the current and voltage pass through zero. However, disturbances superimposed on the mains voltage cause considerable random fluctuations, particularly in the measurement of the times of the voltage zero-passages, which are transferred to the phase angle and can result in an unstable regulation characteristic. It is therefore proposed according to the invention to make use of a reference time for the voltage zero-passage when determining the time difference, which reference time is derived from the measured values for the true times of the preceding voltage zero-passages.

Abstract: A region of the surface of the semiconductor (17) is illuminated with an intensity modulated beam of light (33,38), the wavelength of the light being shorter than that corresponding to the energy gap of the semiconductor (17). The surface photovoltage (SPV) induced in the semiconductor (17) is measured under bias voltage conditions (39). The intensity of the light beam and the frequency of modulation (38) are selected such that the surface photovoltage (SPV) is directly proportional to the intensity and reciprocally proportional to the frequency of modulation. Using the surface photovoltage (SPV) and the bias voltage (Vg) measurements, the charge induced in the semiconductor space charge region (Qsc) and the charge induced in the semiconductor (Qind) are determined. This information is used to determine various parameters of the semiconductor (17) including surface state density and oxide/insulator charge. The apparatus includes a reference electrode assembly (23) which in one embodiment includes a button of insulating elastomeric material and attached to a rigid plate of insulating material. A film (25) of insulating material having the reference electrode (23) at one face is pressed against the specimen with pressure sufficient to hold the reference electrode (23) in close compliance with the specimen (15), with pressure being applied from a backing contact (31). The ac photovoltage signal is capacitively picked up by reference electrode (23) and supplied through an amplifier (41) to a phase sensitive detector (43), the output of which is coupled through an A-D converter (45) to a computer (47).

Abstract: Tungsten-titanium sputtering targets with improved characteristics are made from high-purity tungsten powder and a second powder consisting of high-purity titanium hydride powder or high-purity titanium hydride powder and high-purity titanium powder. The second powder contains at least 5%, preferably 25% to 100% by weight of titanium hydride powder. A powder mixture having a binodal particle size distribution with respect to the tungsten and second powders is placed under a containment pressure in a die. The die is heated in a vacuum hot-press chamber to a temperature sufficient to dehydride the titanium hydride, and to remove gases and alkali metals. The die is then heated to a second temperature in the range of 1350 to 1550<o>C while maintaining the containment pressure and vacuum. A compaction force in the range of 2000 to 5000 psi is then applied to form a compact. The compaction force and vacuum are subsequently released and the compact is cooled. The compact is easily machined to give a sputtering target having a density of at least 95%, preferably, at least 100% of theoretical density, a total gas content of less than 850 ppm, a carbon content of less than 100 ppm and low particulates upon sputtering.

Abstract: Dependent on the quantity of froth produced in a flotation plant, process parameters which indirectly or directly affect the quantity of froth produced are reduced in their quantity depending on the quantity of froth produced. This is effected by reducing certain material flows, including those material flows which are circulated in a flotation plant. Fabrication waters used for dilution are partially replaced by fresh water. This prevents difficulties being caused in the operation of a flotation plant by an unduly large quantity of froth produced.

Abstract: A circuit arrangement for monitoring AC loads, fed via capacitive cable feedlines, in railway signalling systems is disclosed which permits the current flow through the respective load to be reliably monitored by evaluating the current (I) fed into the cable feedline, independently of the length of the cable feedline. The current (I) flowing into the cable feedline flows through a monitoring element (G), which responds to the mean value with respect to time of the current flowing through it, only during one of the half cycles of the feed voltage (U). During the other half cycle of the feed voltage it is bypassed in a low-impedance fashion by a switch (S) controlled synchronously with the feed voltage. Since the capacitive reactive current has the mean value 0 during one half cycle of the feed voltage, the circuit arrangement detects only the real current component, which reproduces the load current, of the current fed into the cable feedline. <IMAGE>

Abstract: Two vertically displaceable slides (5, 9) carry in horizontally movable fashion a tabletop (1) and, respectively, a gripper with an upper gripper jaw (6) and a gripper base (7). The gripper base (7) contains a horizontally displaceable blade (12) and supporting elements (24, 25) which are horizontally displaceable and also vertically movable with respect to the blade (12). A Stack of sheets is set up in front of the tabletop (1). The slides (5, 9) are lowered until the upper gripper jaw (6) rests on the sheet stack. The blade (12), previously retracted into the gripper base (7), is then made to pierce the stack of sheets at an exactly settable distance below the upper gripper jaw (6). The slides (5, 9) are slightly elevated in order to form a gap in the sheet stack with the blade (12). The supporting elements (24, 25) are pushed into the gap below the blade (12), and are then urged upwardly past the level of the blade (12) so that they alone bear the weight of the sheets resting thereon. Upon further elevation of the slides (5, 9) until the tabletop (1) can be introduced into the gap, the blade (12) thus cannot damage the sheets.

Abstract: To deform a sheet material into a wave form, a fixed row (2) of form tools (4) is pressed against a movable row (3) of form tools (5). The form tools of the two rows are in addition simultaneously pushed together, thus reflecting the shortening of the material during the deformation. This ensures that no relative displacement between the material and the end faces (6, 6') of the form tools (4 and 5) takes place even if there are a plurality of shafts with a relatively great height. The movable row of form tools is arranged on a rotor while the fixed row is secured at a work station in the range of rotation of the rotor.
